Title: Capacitive discharge ignition system for an internal combustion engine
IPC: F02P3/08
Filed: 1979-12-11
Abstract: Known capacitor discharge systems have the disadvantage in that increased engine speed is accompanied by a decrease of voltage on the capacitor which feeds the primary winding of the ignition coil, this rendering the known systems little better than conventional circuits at high engine speeds. The present invention seeks to alleviate this disadvantage by providing an ignition spark the energy which is independent of the rotational speed of the engine. Accordingly the present invention provides means 5 responsive to the operation of the engine for periodically producing a signal indicative that an ignition spark is required, a capacitor 10, charging means 13, 14 for charging the capacitor 10, a thyristor 9 operable to discharge the capacitor 10 to produce an ignition spark and trigger means 12 operable to trigger the thyristor 9 repeatedly during a limited period upon receipt of said signal. The means 5 preferably comprise a photo-electric sensor.   <IMAGE>

Title: Card transaction verification
IPC: G07F19/00
Filed: 1980-06-19
Abstract: In off-line verification of transactions involving banking or credit cards, the terminal processes the account number and expiry date, from the card, together with manually-entered PID (personel ident number), in accordance with a function f1 (itself dependent on the expiry date) and compares the result with check digits from the card, to determine whether the transaction is valid. The terminal records whether the transaction is valid and disables itself if more than a predetermined number of transactions within a series of transactions are invalid. The terminal records (e.g. on magnetic tape) all the transaction information together with a checksum obtained according to a function f2 from the transaction information, serial number and validity and the tape identity, so the card issuer can subsequently detect fraudulent alteration of the tape by processing in accordance with function f2 and comparing with the checksum. The functions f1 and f2 are produced by the same algorithm controlled by respective different key information. <IMAGE>

Title: Rolling mill stand
IPC: B21B35/00
Filed: 1981-03-12
Abstract: A rolling mill stand is provided with separate top and bottom housing boxes (14) hinged together at one end and each carrying a centilevered work roll. The rolls are in the form of roll rings mounted on the front extension of a main shaft carried in a main load bearing in the front wall and a reaction load bearing in the back wall of the housing box. Each housing box contains a drive gear integral with the main shaft which is driven by two planetary pinions each coupled to a hydraulic drive motor.

Title: A process for the separation of isotopes
Inventor: CABICAR JOSEF
IPC: B01J20/22
Filed: 1981-08-29
Abstract: A process for the separation of isotopes in two-phase systems, for example, solid phase - liquid phase, liquid phase - liquid phase, solid phase - gaseous phase, is based on the knowledge that the distribution of isotopes can be controlled by the choice of phase composition, that is by their structural and material nature, by the concentration of isotopes and ligands, and further by temperature, illumination, hydrodynamic parameters and by the time interval of contact of phases. For example, uranium, lithium and nitrogen isotopes from aqueous and non-aqueous solutions, or from their gaseous mixtures, if they are contacted with solid sorbents or with liquid extraction agents, can be separated with high efficiency by the above process. The process is, in principle, one of chemical separation.
